Former Huffington Post 'blog editor' Francis Wilkinson wrote a column about how no one pays people to write, anymore, so writing is once again just a hobby of the comfortable, but then he basically admitted that it's all his fault:

After all, the number of people willing to write for free is vast. In 2007, I was in charge of recruiting writers for the expansion of The Huffington Post. I calculated that I would need 75 unpaid blog submissions per day, Monday through Friday, in order to make the site work. That target seemed absurd at first. Yet within two months, hundreds of willing bloggers had signed up, the majority of them credentialed authors published by major publishing houses.

Thanks a lot, Francis!
